This month we have a couple of
interesting articles dealing with
synthetic speech. Wilf R., always
trying to produce more for less,
has come up with a neat little
project for the 1000. Кеп እ.
writes about his Text-to-Speech in
BASIC he demoed last meeting. Gerd
B. reviews the Sinc-Artist Hi-Res
program that utilizes the 8K NVM
add-on written up a couple of
issues ago. If you haven't built
the add-on yet, I urge you to try
it. The cost is minimal and you'll
greatly increase the utility of
your machine. This month we
welcome two new advertisers to our
pages. NOVELSOFT created ARTWORX,
which I think very highly of,
TIMACHINE, only the best MC
compiler availabe for the 2068, and
the new THE WORX. Buy these
programs - your machine will take
оп a whole new complexion. BUDGET
ROBOTICS & COMPUTING is advertising
a new book that the Robot group
should be very interested in.
Remember: our advertisers help keep
YOUR costs done - give them your
business. I realize many of you
still look forward to ZX81 articles
and programs but I can't make such
things appear by magic. Someone
has to submit articles. Most of the
exchange newsletters lean toward
the 2068 and are not a source of
1000 material. I'm doing my bit

„г being the editor; lets have some

lore of you try your hand at ап
irticle or two.

...А new computer paper is out.
CANADA COPUTES is from the
“originators of the highly sucessful
TORONTO COMPUTES. I've made
“arrangements to have a copy for
seach member attending the next
xeting.
»I recently came across an advert
it gave me deja vu. A kit for an
xovative British computer dreamed

up by a chap named Sinclair. No,
not the 2×81 but the QL! Не have
the opportunity to relive those
heady days of discovery.

A+ Computer Response is offering
the Ql in kit form for only sus
139.00. The ZX81 was the most
influential computer ever created.
The 2068 is the probably the best 8
bit computer ever created and
available to the public. The OL is
another ground-breaking machine.
(the only reason bean-counting
Amstrad took the QL out of
production was that their own
machines could'nt match it.
else do you eliminate the
competition if you can't beat them?
You buy ‘em and bury ‘em! Isn't it
odd TIMEX took a similar tack with
the 2068. When they found out they
coudn't match costs with the
dreaded C64, because the the 2068
was a superior machine, they did
what any self respecting
bean-counter would do -- THEY
QUIT!) I know the QL is another
Orphan computer but that never
stopped a true Sinclairphile. Think
of it -- a 16 bit machine for less
than $200.00 lowly Cdn dollars.

e. ¿Parkville member Pan P. has
provided the club with a copy of
the video tape taken at the Cinci
Computerfest last May. As soon as
I make a dup from Beta to VHS, I'll
bring it along to a meeting for all
to view.

.. а couple of new newsletters
turned up recently. We're now
exchanging with S.L.U.G. - the
St.Louis Sinclair Users Group.
P. sent over a copy of the
newsletter of the Spectrum Users
Group Of Australia, and I received
the current and some back issues of
the newsletter of the Sinclair
Users Group of Western Australia.

.. polish up your Polish. With the
recent sale of 200,000 2068s to
Poland and another big sale to
Czeckoslovakia, in no time I'm Sure
we'll be exchanging with User

THE MEETING: Got underway shortly
after 7:00. Bob.D turned up with a
great load of junk, er - good stuff
he was trying to flog, er - sell to
the members. All sorts of strange
and wonderful trinkets to awe the
natives. His wife must have wanted
to use another of the bedroom
drawers and gave Bob the word. Ken
A. wanted to discuss his being
elevated to Pres due to the
stepping down of Bob L. Didn't
think it should be automatic just
because he was V/Pres. We didn't
let him wriggle off the hook that
easily. All Hail Pres Ken. The
Treasurer gave his report -
reporting that advertising income
had increased favourably and that
membership renewals were slow but
steady. The meeting discussed the
matter of Community Centre
membership dues and it was agreed
that if the Centre did not bring it.
up, neither would we. The
Newsletter editor accepted a
rousing round of applause from the
assembled multitude for a terrific
job well done and appealed to all

SINELE TEXT-TO-SPEECH IN 7۳۴

Last spring, ‘you might recall

BUILD A
MICROCOMPUTER-
CONTROLLED

ROBOT

AND OTHER COMPUTER CONTROL PROJECTS

BY B. C. TAYLOR

Are you tired of books which are full of useless projects that
were obviously never built by the author?

Did you ever suspect that the reason some computer project
books didn't show you the completed project is
because the author never built the project as
described or never got it to work right?

Are you intimidated by computer control projects that require
you to build a computer from scratch?

Do you want to learn about computer control and robotics by
actually building and operating equipment that
doesn't cost thousands of dollars?

THEN THIS IS THE BOOK FOR YOU!!!

The centerpiece of the book ie H.E.N.R.Y. the Golden Droid Award
winner at the First International Personal Robot Congress and
Exposition 1984. The book gives complete details во you can
build this internally computer controlled robot for a few
hundred dollars.

The book contains other sophisticated but inexpensive projects and
a supplement with High School robotics course curriculum material.

Over 200 pages (8 1/2" x 11"), with over 80 illustrations and
over 60 tables of information in a builder's notebook binder.

The price is just $15.95 + $2.05 shipping ($18.00 total).

MURPHY'S LAWS OF COMPUTING
People always remember the last mistake you made.

He who hesitates is probably smart.

The one who does the least work always gets the most credit.

The less a peripheral system costs, the more it costs to
fix.

Whatever happens, behave like you meant it to happen.

Confidence is the feeling you get just before you fully
understand the problem.

When you get to the point where you fully understand your
system, its probably obsolete.

As soon as you find that your computer is easy to use, add
some peripherals you don't understand how to operate.

No matter what goes wrong with your carefully planned
database system, there's always someone who says they knew
it would.

It's only when you need to knock on wood that you realize
that the world is entirely made up of aluminum and plastic.

SAN FRANCISCO — A com-
puter hacker with the code name
Pink Floyd has rocked computer
experts’ sense of security.

In the past six weeks, the
hacker has illegally tapped into
computers at Stanford Univer-
sity, Lawrence Berkeley Labora-

tory, the University of Illinois,
Massachusetts Institute of Tech-
nology and at least three un-
identified Silicon Valley com-
panies.

And he's been rubbing the
Computer security forces' noses
in it, as he phones them and bra-
zenly boasts he can't be caught.

So far he's been right. His skill

The Province Sunday, Oct. 5, 1986

has kept police and systems
operators busy but unsuccessful
іл tracking him down. . ۔.‎

One computer scientist who
has helped the search says Pink
Fioyd once was tracked to a
location in Washington, D.C. But
the hunt for the hacker ended
when it was discovered he had
dialed successively through sep-
arate long-distance carriers.

Stanford officials say up to 60
campus computers have been
broken into by the intruder.

They have found no damage to
files or programs but Stanford
has been forced to spend thou-
sands of dollars patching secu-
rity loopholes and changing sys-
tem passwords.

INSTALLATION -

The 2068 has an existing circuitry that
automatically resets the computer whenever the power
switch 15 turned ON. Fig.l] shows this circuit in a
simplified schematic form, The solid lines along with
resistor R43 and capacitor С21 are the existing reset
circuitry. The dotted lines show the required addi-
tional components---the pushbutton (P.8.) to provide
the means for manual RESET (whenever you wish) and
capacitor CR to provide positive initialization on
power up.

SCROLLER

by Theo Turk
For the 15-1000/1500/2х-61 July 7, 1986

This program, like my previous one is a basic "Scroll left"
routine. However, with my last one, I could only enter a 64
character message into memory. This program not only allows
you to enter any message up to 15K characters in length but
will also let you use various "flash words" in your message
to emphasize certain portions.

There are various reports given, if in error. A report
code of "2" means either that line 10 has been omitted ог that
one of the "flash words" is not enclosed by parenthesis.

A report code of "B" means that you are trying to enter an empty
string, or the length of the message in AS is <32 characters
long or the length of a flash word is »25 characters long.

Keep in mind, each "flash word" must be enclosed by par-
enthesis and with any two flash words, the first character in r
each flash word (example 1) must be separated by ›=32 characters.

TYPE IN THE FOLLOWING LINES:

TO see what happens, RUN the program and in a few minutes

example...

If the display seems to working correctly, press "break"
and delete lines (2 to 9).

NOTE. to introduce "flash words" into any message, simply enclose

each one in parenthesis.
to terminate the program, press "break". NOTE: any error
return or "break" will destroy part of the message stored.

TIMEX TIPS
By Chuck Dawson

QUESTION: I am neu to machine code programs and I would like to
ask a basic question: If I call a short MC routine from within
‚а BASIC program, how do I get the result back to а BASIC
variable so I can use it?

ANSWER: This question keeps being asked, so I am glad to try
to help. There are two ways to approach this problem. When a
number has been manipulated by the various registers, it can be
stored for later use by loading it into an unused memory
location (or more usually two). After returning to BASIC, the
number can be recovered by LET A=PEEK loc + 256xPEEK (1ос+1).
Several numbers could be calculated by the MC part of the
program and stored in different locations. All you have to do is
remember where you put them. If the MC routine produces only one
answer to be transferred to the BASIC program, а short-cut
method is to leave the answer in the BC register (1715-2069 and
Spectrum) ог the HL register (75-1000 ог 75-1500). If the
routine was called by the line LET a=USR (64000), then when the
MC routine RETURNs control to BASIC, the value that was in BC
will mow be in the BASIC variable A. If you called the routine
with PRINT USR (64000), then the answer will be printed on the
‘screen upon RETURN `

QUESTION: I have a problem with a program which includes user
defined characgers. It works just fine in the normal mode, but
when run with the 05-64 (64 column cartridge), the user
characters do not work.

ANSWER: When the TS-2068 is switched into one of the enhanced
display modes like the 64 column, the user defined graphics are
moved from 65386 to 63256. If you have defined a character for
GRAPHIC A, for example, by POKING values into addresses starting
at 65386, then you have poked the wrong location when in
enhanced mode. It should have been 63256. You would have to
change that location each time you switch from one mode to the
other. A good way out of this is to use the built-in GRAPHIC
ADDRESS CALCULATOR. That is, calculate the starting address of
GRAPHIC А by the expression LET address-USR 'A'. Then you сап
POKE address and address*1 and address*2, etc. No more changing
the program by hand each time you plug in or out the 64 column
cartidge. By the way, if you like to put machine code in a КЕМ
Statement at the beginning of your program, it, too, will move
when in enhanced mode. Always use PEEK 23635*256x*PEEK 23636 to
calculate the beginning of the program listing. Add five to get
the correct USR call location if the MC starts just after the
REM keyword in the first line of the program.
